Perhaps buy a 'swivel spout mixer' that's a similar height, but swivels and 'swings' out of the way of the basin. A company called Reich do them (but there are others ). Not cheap (£50+) but will do the job.

Can't quite see from your pic if there's any microswitch wires leading to your tap, but if there are, it's probably just a case of one tap assembly off and drop the other one in. The assembly is normally screwed and held by a base plate underneath the worktop. You may be able to use the original hot & cold 'tails'. If not, the tails can be bought separately. A phone call to fellow Funster @Johns_Cross_Motorhomes is someone who could give advice.

Looks like you've got pretty good access, so should be a breeze. I've fitted similar to a previous MH of mine and a plumber, I ain't!!!
Let us know how you got on.

Thanks James for your helpful comment, it would be handy if the height permitted the rinsing of any item. We have become used to having twin sinks in our home kitchen and when space is at a premium it's not always possible to do the whole lot sequentially. It's a small matter the Autocruise Augusta has the 'novel' sink on one side of the van work-surface on the other. That feature was corrected on the later Swift version.
